Improvement in plows



UNITED STATES PATENT OFFICE.

LORENZ WOLF, OF HAMBURG, MISSOURI.

i IMPROVEMENT IN PLOWS.

Specification forming part of Letters Patent No. 31,136, dated January 15, 1861.

To all whom it may concern:

Be it known that I, LORENZ WOLF, of Hamburg, in the county oi' St. Charles and State of Missouri, have invented a new and useful Improvement in Plows; and I do hereby declare that the. following is a full, clear, and eX- act description Ot' the same, reference being had tO the annexed drawings, making part of this specification, in which- Fignre l is a top view ot' my said improved plow. Fig. 2 is a side elevation; Fig. 3, atop view of the improvement only. Fig. 7 is a transverse section on the line A A. Fig. 6 is a back elevation of the plow without the beam Or tail. Fig. 4 is a top view, and Fig. 5 a side elevation, of a cultivator of double moldboard, to be applied to the frame of the plow whenever it may be desired, by removing t-he common one-sided plow.

My invention consists in a novel method of ironing the plow, the frame being made in the ordinary manner.

To enable any one skilled in the art to which my invention appertains to make and use the same, 1 will proceed to describe the construe tion and Operation thereof.

Similar letters of reference represent corresponding parts of the drawings annexed.

In the drawings, A represents an iron strap bolted to the under side of the plow-beam. The

said strap has a curved end, t, to which the team is applied by means Ot' the ring b, the object being to prevent the clevis from uniiooking. This strap is connected toa plate, D, which is also fixed to the under side ofthe plow-beam and which has amortise cut through it, into which the vertical beam H is made to tit accurately against the sides of the said mortise, but not against the ends thereof". This vertical beam H is raised or lowered by means otl the key R, the top of which has graduated notches in it for that purpose. By this means the point of the plowshare :may be depressed or elevated, as the case may require. rIhe beam H is secured in the plow-beam by means of the key P, applied as shown.

In the back end of the plate D there is a lug, I, fixed to reach up in a mortise made in the under side of the plow-beam, as shown in Fig. 7. Through this lug a hole is bored, in which a left-hand screw-thread is cut to receive the screw c, which is also left-handed to match the thread in the hole in the lug. The end of this said screw is made smaller than the body thereof, and on it a screw-nut is placed with a right-hand thread. Now the object of this screw is to slew the point of the plowshare in one direction or the other, which is effected by simply turning the screw which carries the back end of the plate D either to the right or left, and as the beam H tits in the said plate the point of the plow must ofcourse be et'- fected whenever the position ot' the plate is changed.

The mold-board B and landside J are made in one piece, and are braced by means of aa brace, K, and are bolted to the heel of the plow-tail and to the beam H by means of loose bolts and the lng Q, which is fixed to the inside Of the mold-board.

The beam EI must be made straightand fixed directlyin the center Ot' the beam and in front Ot' the heel of the tail, so that aright or a left hand mold-board can be applied to it without difficulty. Figs. 3 and 6 show a left-handed moldboard applied, and Figs. 1 and2 show a righthandcd one applied. By making and arranging the beam H as described one plow-frame will answer for every purpose, it being only necessary to have dii'erent mold-boards and cultivators of such size and shape as may be required.

Having thus described the construction and Operation of my improvement in plows, what I claim, and desire to secure by Letters Patent, is

The arrangement of the standard H, the plate D, the lug I, and screw C, in connection with the plow-beam and the plow, substantially in the manner described, for the purpose specified.

LORENZ WOLF.
